Observance of all listed below norms and requirements to carrying out procedures of the general and major maintenance of the car and its components will allow to perform all works at high professional level.

Interfaced surfaces and laying

At the partition of the components joined among themselves at all do not hook them a screw-driver, mount or any other lever entered between interfaced surfaces. Such practice is fraught with the serious damages of details conducting to development of leakages of working liquids in the near future as a result of violation of tightness of a joint. If details "became attached" to each other and do not give in to a partition, обстучите them on perimeter a hammer with soft brisk for the purpose of destruction of a layer of sealing hermetic. It is necessary to notice that such way can appear inefficient in case of existence of directing pins.

If between interfaced surfaces of two components sealing laying is established, at assembly it is necessary to replace it without fail. Laying should be established dry if the return especially is not stipulated in the description of procedure of assembly. Before installation of new laying carefully smooth out interfaced surfaces of components, having completely removed from them the remains of a material of old laying, and hermetic traces (if that is applied). For cleaning of surfaces use only the tools, not capable to damage metal of which components are made. Minor defects can be removed by means of a file with small tooth.

Carving openings clean by means of the special adaptation for pro-cleaning of tubes. If the return especially is not stipulated in the description of procedure of assembly, do not grease a carving of fixing bolts with any hermetics or greasings.

Before a sostykovka of components make sure of passableness of openings of all galleries and маслотоков. For reliability blow them the compressed air.

When using the compressed air do not forget to put on goggles!

Epiploons

Extraction of epiploons from the landing nests is made by a poddevaniye by their screw-driver with a flat sting or other suitable tool. Alternatively, pair can be screwed in a face surface of an epiploon саморезов which heads then it will be possible to grasp nippers.

At assembly replacement of epiploons is made without fail.

Remember that extremely thin sealing sponges of epiploons can be easily damaged. Existence on walls of a landing nest of an epiploon or a pin of a condensed shaft of agnails, задиров and deep scratches leads to fast development of leaks at the expense of damage of sponges of a new epiploon. If restoration of surfaces contacting to an epiploon is not obviously possible by their machining, replacement of worn-out details is made.

Before installation take care of protection of sponges of an epiploon against damage to landing process by a coiling of dangerous sites of contact surfaces an adhesive tape or other suitable material. Whenever possible use conic opravka for ensuring smoothness of landing of epiploons. Before installation surely grease epiploon sponges. Between sponges it is necessary to fill a cavity with dense greasing.

If the return especially is not stipulated in the description of assembly procedure, epiploons always should be established by sponges inside (to a condensed cavity).

The press fitting / застукивание an epiploon in a nest is made by means of an opravka as which the face head of the suitable size or a piece of a pipe of the corresponding diameter can act. Epiploon landing in a nest is made against the stop it in a casing coat hanger. If a coat hanger is not provided, the epiploon is put aflush with a face surface of a casing (if the return especially is not stipulated in the description of procedure of installation).

Fixture and carving openings

The "become attached" bolts and nuts for simplification of unscrewing and in order to avoid damage before an otdavaniye should be processed by special getting structure. Many mechanics prefer to use for this purpose turpentine which it is convenient to put from the special small canister with a long nouse. After wetting of the "become attached" fixture it is necessary to give to getting structure within several minutes properly to impregnate the oxidized contact layer. Strongly rusted fixture can be cut down by a chisel, is cut by a hacksaw or removed by means of special гайколома.

For a reversing of a hairpin screw on its end two nuts and законтрите them from each other, having formed similarity of a head of a bolt. Throw an internal nut with a rozhkovy key and turn out a hairpin as a usual bolt. When cutting a head of a bolt or a hairpin oblamyvaniya on assembly, the rest of a carving part can be drilled or taken by means of a special ex-tractor. The majority of repair trucks can undertake performance of this, also as well as others (for example, restoration of the broken carving in carving openings) repair procedures.

Before a fixture vvorachivaniye in deaf carving openings surely check, that in the last did not remain any traces of oil or moisture - increase of hydraulic pressure in an opening cavity at a tightening of a bolt can lead to destruction of the case of a component.

To achieve combination of a groove of a koronchaty nut with an otversty opening under installation шплинта in a body of a bolt/hairpin tighten a nut with demanded effort (if the last is stipulated in Specifications), then hold on a nut further before combination with an opening of the next groove of a crown. At all do not weaken a nut for combination of openings!

For correction of effort of a tightening of fixture weaken a bolt/nut on a turn quarter, then tighten with demanded effort. The last technique does not belong to cases when at the last stage the fixture reaches on the corner stipulated in Specifications.

Lock-nuts and lock washers

All fixture rotating concerning the case of a component, at a tightening should be without fail completed with a washer.

Spring and engraving washers after an otdavaniye of fixture are subject to replacement. The same treats lock washers with bent tags.

Самоконтрящиеся nuts in noncritical knots can be used repeatedly, under condition of existence of a certain resistance at a navorachivaniye. It is necessary to notice that efficiency of functioning of kontryashchy structure in a nut carving considerably decreases over time, and therefore, it will be more correct to replace such fixture after each otdavaniye.
